CBGB Documentary from 1978

Features the Ramones, Blondie, and the Dead Boys.  The cheesy narrator adds to the overall effect.  His tone is deadpan but also shocked – shocked! – throughout.  Totals to 51 minutes, you'll want to watch it through if only to see the clueless music critics trying desperately to commentate on the whole glorious mess.  You might want to embiggen.
